Analysis and actions after laboratory errors in a Chinese university hospital

Preanalytical errors are the most prevalent LEs, often originating outside the laboratory. Cognitive errors are highly preventable. Implementing targeted interventions based on systematic error classification and root cause analysis-including technological solutions (e.g., electronic alerts, LIS improvements), workflow simplification, enhanced training (especially for non-laboratory personnel in transfusion contexts), and interdepartmental communication-significantly reduces LEs and enhances laboratory quality management. Continuous monitoring and context-specific strategies are crucial, especially in large healthcare systems. Study limitations include potential underreporting and limited generalizability beyond specialized women and children's hospital settings.
